In a study conducted to investigate browsing activity by shoppers, each shopper was initially classified as a non-browser, light browser, or heavy browser. For each shopper, the study obtain a measure to determine how comfortable the shopper was in store. Higher scores indicated greater comfort. Suppose the following data were collected.

LIYIIL Heavy Nonbrowser Browser Browser CO 10 12 10 12 10 9 11 10 Co 12 a. Use a = .05 to test for a difference among mean comfort scores for the three types of browsers. Compute the values identified below (to 2 decimals, if necessary). Sum of Squares, Treatment 76.6 X Sum of Squares, Error 24.5 Mean Squares, Treatment 26 Mean Squares, Error 1.17 Calculate the value of the test statistic (to 2 decimals, if necessary) 22.29 The p-value is less than .01 What is your conclusion? Conclude that the mean comfort scores are not all the same for the browser groups b. Use Fisher's LSD procedure to compare the comfort levels of nonbrowsers and light browsers. Use a = .05. Compute the LSD critical value (to 2 decimals)
